AvMath vs XYmajor

AvMath is a mental math education and training tool for pilots to improve their mental math skills. Whether you are a student, private or commercial pilot you will learn rules of thumb and methods for quick calculations of speeds, distance, altitudes and time, then challenge yourself to train and improve applying these in realistic aviation scenarios. Every answer is explained in detail while you track your improvement with records and achievements and challenge yourself with increasing levels of difficulty. Learn common Rules of Thumb - Crosswind Component - One in Sixty - Density Altitude (inHg and hpa) - True Airspeed - Vertical Navigation - Drift Angle Apply in Real Aviation Scenarios - Crosswind - One in Sixty navigation - Enroute Wind - Fuel Planning - Vertical Navigation - True Airspeed - Density Altitude - Descent Planning - Quick Calculations - Trip Planning

Learn the 10 Key Consonants – Memorize them thoroughly. 2. Master the First 100 Cards – Remember the story vaguely for each using pegs 00–99 as anchors. 3. Master the Next 100 Cards – Use pegs 500–599 as anchors for these cards, following the same method. 4. Track Your Learning – Use the XYdata peg to review each peg at least 4 times. The AI FSRS monitors your progress and adapts to your memory patterns. 5. Follow AI Review Schedule – The AI FSRS will tell you when to review each peg (via peg status) to maintain ~95% recall. Learn Anything, Fast: Once your pegs are secure, use them to lock in new information—like vocabulary for kids—with the help of vivid, AI-generated images.
